do masks require tpu hot melt adhesive membrane?

do masks need hot melt adhesive membrane? this question can be said to be a very hot issue in the hot melt adhesive industry recently. we are already very familiar with the application of hot melt adhesive membrane in clothing, shoe materials and other fields, and whether it can be used in the mask industry seems to be rarely mentioned. so, does hot melt adhesive membrane need to be used in the processing and production of masks?

there is very little information on the internet about whether hot-melt adhesive membranes can be used for masks. this is mainly due to the particularity of masks. masks are different from clothing, shoes and other items. masks fit directly on the face. the quality of masks will have a direct impact on our health. hot melt adhesive membrane, as a chemical adhesive, gives people the impression that it may have an impact on people's health. therefore, when faced with the question "do masks need hot melt adhesive membrane?", the answer is basically no!

in fact, it is not that hot-melt adhesive membranes cannot be used in the production and processing of masks, but the standards for hot-melt adhesive membranes used in mask lamination are different from those used in clothing, shoe materials, etc. after all, masks fit our faces, and the adhesives required to be used are usually medical grade or food grade.

in the past, due to various factors such as the market, the market demand for this type of hot melt adhesive film was not very large. therefore, the output of this type of hot melt adhesive film is not large, and even few manufacturers will focus on this aspect of research and development. affected by the current epidemic, we have also urgently increased the research and development of hot-melt adhesive membranes for masks. currently, the hot-melt adhesive membrane for n95 mask composites has been mass-produced, and the current daily production capacity is 150,000 meters.
